LCD driver based on FrameBuffer frame of STM32MP157 What is FrameBuffer? Framebuffer is translated into Chinese, that is, frame buffer. Frame is the smallest unit in image animation. A frame is a still picture, and continuous frames form animation. Then frame buffer is used to cache the data of a frame. In the linux kernel, it is a program in ...

The structure of the hospital area is shown in Figure 1. The walls on both sides of the hospital corridor are represented by black solid lines. The corridor floor is pain ...

First, the concept of IIC is omitted. It's written in detail on the Internet. Let's start with the CUBEMX configuration code. The project in hand is a host and seven slaves. The slave uses the middle transceiver. The address is a big pit, and the subsequent read-write interrupt is also a pit. Slave address: The hardware is I2C_ ADDRESSINGMODE ...

4.3 verify the implementation effect of OpenMIPS 4.3.1 implementation of instruction memory ROM In this section, we verify whether OpenMIPS is implemented correctly, including whether the pipeline and ori instructions are implemented correctly. The instruction memory ROM is read-only, and the interface is shown in the figure: `include "defin ...

Design task (function introduction) A four digit BCD code calculator is designed based on AT89S52 single chip microcomputer. The specific functions are as follows: Realize the addition, subtraction, multiplication and division of 1 ~ 4-bit BCD code and integer operationKeys 0-9 represent numbers 0-9, respectively. A is the plus sign, B is the ...

preface You can't play electronics without an oscilloscope, and you can't go whoring with a school oscilloscope after graduation. As the saying goes: no conditions create conditions. If there is no oscilloscope, create an oscilloscope. It sounds tall, but it's not difficult. There are many open source oscilloscopes on the Internet, the m ...

summary The title of all the work to be done in this paper basically includes reading the temperature value of the temperature sensor, and then printing it to the serial assistant through the serial port; A lot of bloggers' great God's tutorial I always follow the steps to make the program do not report errors and detect the sensor's condition ...

preface    in the last course, we learned about nixie tube and realized the static display of nixie tube through code. This course will continue the content of the previous lesson and explain the dynamic display of nixie tube.   tip: I learned about nixie tube last class, so I skipped the explanation of nixie tube and b ...
